Description

A 8.2 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (8.2 Ohms):

This resistor has a resistance of 8.2 ohms, meaning it provides a moderate opposition to the flow of electrical current. An 8.2-ohm resistor is typically used in circuits where you need to limit current, create voltage dividers, or match impedances. It is often found in low to medium power circuits, including those involving signal conditioning, LED current limiting, or simple power regulation.

Power Rating (1/4W):

The 1/4 watt (0.25W) power rating means the resistor is designed to safely dissipate up to 0.25 watts of heat. The relatively low power rating is suitable for typical low-power applications, where the current through the resistor is not large enough to cause excessive heat generation. The 1/4W rating ensures it can handle heat dissipation safely during operation.

Tolerance (5%):

The 5% tolerance means that the actual resistance of the resistor can vary by up to ±5% from its nominal value of 8.2 ohms. This variation gives the resistor a range between 7.79 ohms and 8.61 ohms. While there is some variation in resistance, this is standard for general-purpose resistors and is usually acceptable for most typical electronic applications where precise accuracy is not critical.

Through-Hole Mounting:

This resistor is designed for through-hole mounting, meaning it has leads that pass through holes in a printed circuit board (PCB) and are soldered to the opposite side. Through-hole mounting offers strong mechanical stability and is ideal for situations where durability, reliability, and ease of component replacement are important. This type of resistor is commonly used in both prototyping and finalized designs.

Applications:

• Current Limiting: The 8.2-ohm resistor is often used to limit the current in low-power circuits, such as LED drivers or current-limiting applications for other sensitive components.
• Voltage Division: This resistor can be used in voltage divider circuits to create specific voltage levels for powering other components in a system.
• Impedance Matching: In audio and signal processing circuits, it can help match impedance between components to ensure optimal signal transfer and minimize losses.
• Filtering and Decoupling: It can also be used in filtering circuits, providing resistance to smooth out fluctuations in voltage or current, improving the stability of the circuit.

Summary:

The 8.2 Ohm 1/4W 5% Through Hole Resistor is designed for use in applications that require moderate current limiting, voltage division, or impedance matching. The 1/4W power rating ensures it can handle the heat dissipation requirements of typical low-power circuits, while the 5% tolerance offers sufficient accuracy for most general-purpose applications. The through-hole mounting style provides a durable and stable connection, making it suitable for both prototyping and final circuit designs.
